Analysis and Optimization of Early‐Warning Indicators for Impact Critical Stress in Deep Soft Coal Seams

Energy Science &Engineering, Volume 14, Issue 8, Page 3726-3740, August 2026.
This study determines the impact critical stress early‐warning indicators for deep soft coal seams: 18 MPa (shallow holes), 20 MPa (deep holes), and 3 MPa/d daily stress change rate, via theoretical, experimental and simulation methods. ABSTRACT The accurate determination of early‐warning indicators for critical impact stress in deep soft coal seams is

Numerical Modeling of Geological Fault Reactivation Using Sequential Coupling Strategies

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 11, Page 4339-4359, 10 August 2026.
ABSTRACT The interaction between fluid flow and mechanical deformation in fault zones can lead to processes of fault reactivation, triggering potential geomechanical problems such as seismicity, well collapse, fluid migration to shallower layers, and aggravated surface subsidence.

Techniczna Teoria Zginania Prętów dla Pewnego Przypadku Materiału Fizykalnie Nieliniowego

Engineering Transactions, 1962
The non-linear stress-strain relation is assumed, in the uniaxial state of stress, in the form ε = sgn σ * a | σ |n. Pure bending of a bar is considered in the general case (any direction of the vector of the bending moment).

Uncovering hidden bias in neutron diffraction residual strain measurements

Journal of Applied Crystallography, Volume 59, Issue 4, Page 991-1004, August 2026.
This work demonstrates that diffraction‐based residual strain calculations and uncertainty estimates depend on how grain populations are sub‐sampled, with important implications for interpreting residual stresses in heterogeneous materials with fine‐scale microstructure and strain gradients.When calculating residual strain via neutron or X‐ray ...
